`Specification of Letters Patent Patented Aug. 29j, i916.

Application led J' uly 17, 1914:. Serial No. 851,595.

To all whom t may concern Be it known that I, ARTHUR B. NoRRIs, a citizen of the United States, residing at Rochester, in the count chines, of which the following is a specification.

My invention relates, more particularly, to woodworking machines for removing the stubs which remain lon the toe and heel portion relates is that involving a rotarycutter for .o-peratingon the lasts, guided in its cutting movements by operative connections between it and a tracer-element adapted to be revolved about ythe end of a pattern, or

form, the contour of which corresponds to the contour it is `desired thel lasts should present, and a work-support adapted to support the work to be operated on and movable relative to the cutters for feeding the work to the latter as the cutting operation progresses.

' My objects, generally stated are to generally improve upon machines of this type as hitherto constructed so as to cause them to better perform the work yfor which they are provided.

Specifically stated, my primary objects are to provide improved work-holding de.-u vices which shall be adjustable for reversing the ends of the work to permit the cutters to operate on both ends of the lasts without rea'dj'usting the work oni'the holder, adjustable for varying the throw.of the holder in reversing it, and adjustable for work of different sizes; to provide improved means for reversing the work-holder and releasably locking it inposition; to provide improved bearings for lthe carriage supporting the work-holder; to provide adjustable stopdevices for limiting the upward movement of the work-holder carriage i-n repositioning it after completing the cutting operation on the work while the holder is in one position, which may be adjusted .to cause the carriage to be automatically arrested, when lifted, at different heights, depending on the aXial position of the work-holder; to provide automa-tically-operating means for of `Monroe and,V State of New York, have invented a new and useful Improvement i'n Woodworking-Madisconnecting the driving means controlling the rotary movement of the' cutters about the Work; to'provide improved means'con-v trolling the descent of the work-holder-carriage; to provide al hand-feed for the workholder-carriage; to provide improved clamping means for securing the work against movement on the Work-holder; to provide for the adjustment of the cutter and pattern-tracer spindles; to provide guardmeans for protecting the operator from injury by the cutter-blades in operating the machine, and automatically operating means for moving `the guards to operative position; and to provide improved means for cushioning the counterweight controlling the work-holding-carriage in its movement.

Referring to the accompanying drawings,

Figure l is a lview in Aside elevation -of a woodworking machine embodying my improvements. Fig. 2 is a similar View taken from the opposite side of the machine. Fig. 3 is a front view of the machine. F i is a rearview of the machine. Fig. 5 is a planview of the machine, a portion of a cover for certainy parts of the mechanism being broken away. Fig. 6 is a plan view of a portion of the machine with certain parts removed, showing a portion of the mechanism for actuating the tracer and cutters in continuous paths, the mechanism being shown in. a position it assumes aftenrthe cutting operation has been completed andv just before the automatically Aoperative mechanism fory arresting certain driving4 mechanism has been brought into operation. Fig. 7 is a broken View in section, the section being taken at the line 7 on Fig. 6 andv viewed in the direction of the arrow. Fig. 8 is a view similar to Fig. 6, with the coverplateof Fig. 6 removed, the automatically operating drive-arresting mechanism being shown in the position it assumes after it has operated to arrest'the drive. Fig. 8a is a detail view in "elevation, partly sectional, of a portion of the automatic stopping mechanism shown inFig. 8. Fig. 9 is 'a section taken at the irregular line 9-9 on Fig. 11 and viewed in the direction of the arrow. Fig. 10 is a section taken at the line 10 on Fig. 11 and viewed in the direction'of the arrow. Fig. 11 is a section taken at theline 1l on Fig. 10 and viewed inthe direction of the arrow. Fig. l2 1s a View in elevation, partly sectional, of a portion work-holder opposite to that shown in Fig.

16. Fig. 20 is a section taken at the line 20 l of the stud which is operatively connected with the pattern-tracer and -cutters and through the medium of which said tracer and cutters are driven about the ends of the pattern and lasts. Fig, 13 is a sectional view taken at Vthe lin'e '13 on Fig. 1 and viewed in the direction of the-arrow, showing the positions occupied by the` patterntracer and cutters. relative tothe work to be operated on, during the cutting-operation.

Fig. 14 is an enlarged sectional view taken' at the line 14 on Fig.- 3 and viewed in the direction of the arrow, this view, by full lines, representing the positions occupied p 15 by the reversible work-holder and its reversing means, when the toe-portions of the4 lasts to .be finished are being operated on, and by dotted lines the-positions occupied by 'these parts When'the work-holder is re- Oyersed'to present theheel portions. to the' cutters. Y Fig. 15 is a broken section taken at the line. 15 on Fig. '14 and Viewed in the direction ofthe arrow. Fig. 16' is a' faceview of a portion of one endY ofthe workholder. Fig. -17 is a face view of one of. the

adjustable bars carrying'clamp devices for' the lasts and modeL-,or pattern. Fig. 18 is va similar view Aof the other adjustable. bar coperating with the bar of Fig. 17. Fig. `19"is a brokenfaceview of the ed e of the on Fig.. 18 and viewedin the .direction of the arrow, this view showing the detail of -one of the plurality of similar devices on the work-holder, for holding the work and pattern inv place. Fig. 21 is a sectiontaken at the line 21 on Fig. 16 and viewed in thedi'- rection of the arrow, with a .key shown in 'elevation and in position for adjusting the bars4 of Figs. 17 and 18 relative to each other. Fig. 22 is a section taken at the line 22 on Fig. 13 and -viewed in the directibn of the' arrow showing the) work-holder and 5' the manner of clamping'a piece.of Work in p osition thereon.
